PRODUCT DETAILS
Overhead Hoist Transport (OHT)
Streamline material handling with Overhead Hoist Transport (OHT), offering efficient, automated solutions for seamless
movement of goods in high-tech manufacturing environments like semiconductors and electronics.
Overhead Hoist Transport (OHT)
The Overhead Hoist Transport (OHT) system is a cutting-edge solution designed for material handling within semiconductor FABs. It facilitates the seamless transportation of materials between different process areas (inter-bay) as well as within specific zones, including manufacturing equipment, testing equipment, and the Stocker (intra-bay). Renowned for its advanced automation capabilities, exceptional efficiency, and ability to maintain a clean, low-vibration environment, the OHT system plays a crucial role in optimizing the productivity and reliability of high-tech manufacturing processes.
